This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Current Description
The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.

Translation
La implementación de la escala Montgomery en OpenSSL hasta la versión 1.0.0l no asegura que ciertas operaciones de intercambio tengan un comportamiento constante en el tiempo, lo que facilita a usuarios locales obtener nonces ECDSA a través de un ataque de caché de canal lateral FLUSH+RELOAD.
